Yum --exclude broken?

[Janina Sajka]

I'm suddenly unable to update/upgrade with yum. Seems mozilla has been
marked at version 37 in one of the repos.

So, no problem, I say to mmyself, and issue:

yum --exclude epiphany update

but to no avail. So, is it yum, or something I'm doing wrong? Anyone
else get anything similar?

With yum-2.1.3-1
